ABSTRACT In a period of 6 years 144 asymptomatic boys with cryptorchidism, of mean age 7 +/- SD 3.5 years, underwent orchiopexy. None of these boys referred to a history of a known urological anomaly, urinary tract infection, haematuria, palpable mass in the renal region, bladder extrophy, epispadias, hypospadias or anorectal malformation. On the third day after orchiopexy and intravenous pyelography was done in every boy following testicular protection against irradiation. Ultrasonic investigation was not available at that time. There were minor urological abnormalities in 36 (25%) boys and major ones in 8 (5.5%) boys. A major anomaly is defined as one resulting in significant loss of renal substance (one case of single kidney and three cases of unilateral renal hypoplasia), or requiring surgical correction for conservation of the renal substance (one case of ureterocele, two cases of pelviureteric stenosis and one case of vesicoureteric stenosis with ipsilateral hydronephrosis). The unsuspected major urological abnormalities are usually ipsilateral to the more undescended testis. They may be associated with a hernia and are more frequent in bilateral cryptorchidism. In conclusion we encourage the routine use of IVP, or ultrasonic investigation or dynamic renal scanning (99mTc-DTPA), if it is possible, in all patients undergoing orchiopexy for the detection of an unsuspected major renal anomaly.

    ABSTRACT: Ultrasound has become the modality of choice for the evaluation of the neonatal genitourinary tract. High frequency linear, vector, and curved array transducers (7 MHz, 5 MHz, 12 MHz) and portability of the equipment make a rapid bedside evaluation with exquisite anatomic detail possible. A major advantage of sonography over other modalities is real time observation and circumvention of sedation.

    ABSTRACT: Although cryptorchidism is probably the most frequent genital anomaly encountered in boys, this pathology remains largely unexplained and its long-term prognosis is still uncertain. Despite the relative easiness of this diagnosis, attention should be paid to some clinical traps, which can mislead the sexual identity. Indeed, beside the isolated common cryptorchidism, many troubles of the testicular migration can be associated with various malformative syndromes and can be named as “cryptorchidism symptoms”. Most of these syndromes are obvious, but some can be suspected only by the way of an abnormal descent of testis. Cryptorchidism, which is systematically screened out during any pediatric consultation, should play the role of clinical marker for various endocrine or genetic disorders. Among them, the intersex states should be underlined to avoid the harmful effects of misdiagnosis. We dealt with this subject through a clinical and practical approach.

    ABSTRACT: The prevalence of 54 minor morphological aberrations (MMAs) (mild malformations, dysplasias, deformities and phenogenetic variants) was determined in 138 children with isolated malformations of the urinary tract and in 32 patients with multiple major birth defects including renal malformations. Children with infectious diseases matched to each patient by sex, age and ethnic origin served as controls. The overall prevalence of MMAs--expressed as MMA/subject ratio--proved to be significantly higher in patients with multiple malformations (2.50) than in those with isolated renal abnormalities (0.80) and in controls (0.76). The difference between the latter two groups was not significant. Apart from characteristic patterns of well-defined syndromes, the only specific association found was the higher prevalence of supernumerary nipples in patients with isolated (and hidden) urinary tract abnormalities of various types (9.4% versus 1.8% in controls; P less than 0.005).
